1. If you failed to use the shader files, try to disable hardware vertex processing in Awakening's "Change Device..." dialog.
2. If you use terragen to create terrain, please set terrain size to 129 x 129, otherwise terrain mesh will too big due to the limit of 65536 vertices.
3. The sun is too big? Try set the G value in Henyey Greenstein approximation function to a bigger number.
